issue with Routing and 4G/Wifi Modems on 15-current

HI !

Using the iwlwifi driver with AX201 intel chipset works to local home WIFI router whit no issues other than the well known speed situation limited to 11g standard.

Attempting to switch the connection to a 4G/Wifi modem is less successful.
after the switch its possible to login, with firefox browser, to the modem and look at its setting traffic volume and other admin stuff.
therefore point to point , laptop AX201 <-> 4G/WIFI modem is operational

Routing does not work.
restarting service local_unbound and restarting firefox does not fix the situation, stopping the PF firewall does not help.
running " netstat -nr" shows default gateway switched to 4G/WIFI modem. ip address and subnetwork has also been updated.
using port /usr/ports/net-mgmt/wifimgr i can switch between the two networks.
but routing isnt operational over the 4G/WIFI modem .

Is this an known situation ?
 
Details on the modem please. Brand and Model. Mobile Carrier you are attempting to connect to.

Show output of ls /dev/ttyU*

I missed this point. So can I assume this is a Huawei modem??? I dont have any experience with them. I bought one once and the config interface was horrible.
I am Sierra guy and have to use AT codes for config.

I assume you are trying to use an network interface ue0 to connect?
 
Personally I like to use KISS principals. When you have two interfaces like this with wifi and cellular you have saved routes and all kind of complications.
KISS dictates one device only. Get the cellular modem working. Remove all vestages of wifi settings.
Cellular Modem settings are fickle and depending on mobile carrier. So eliminating wifi helps make a clearer path of troubleshooting.
Is it a FreeBSD problem or the carrier/modem settings.
 
Once you get the cellular modem connecting you can figure out how you want to work with two networks. Wifi and Cellular.

Do you want LAGG failover from Wifi? How are you planning to deal with two providers? Much needed details.

If you have everything working connection wise and this is the issue then it don't suprise me.

net-mgmt/networkmgr seems more apt at switching between wifi networks and does not handle multiple network devices well. (No offence Eric)

You may need to consider other methods. LAGG is good choice. Wifi when in range failover to cellular.
 
HI,

After I added Björn Zeeb's settings for enabling high speed comms to iwlwifi , which works with the home Router,
DHCPDISCOVERY/REQUEST was no longer possible with the old 4G/Wifi modem.
So I decided to source a new modern 5G/WiFi modem to use at mobile locations.
so this investigation is put on hold until then ..........................
